CRoS Patented Aug. 6, 1946 UN-IIED- STATES P ZASA This. invention relates to display mounts and more'particularlypertains to the hinged panel or door sections embodiedjinthe display meunts.

Heretofore V displayjmgunts have embodied hinged portions suchas picture or calendan-im sert portions, easel portions; hang-up tab portions,

and the like. Mounts of the display type and particularly those used ,for advertising purpo ses, must be produced at a minimum cost and for this reason, for want of'a better expedient it has been th'e'practice to score the: mountmaterial to form a hingeilineij However; a hinge line formed by a scoring operation is not entirely, satisiactory because movement of a mountsection about such a hinge places a greatstrain on the ad acent portion of the mount. In many instances thisstrain is suificient to destroy the utility of the mount in a short time, for such mounts are usuallyQmade of cardboard havingnogreat inherent strength.

Thi invention is based on the appreciation of thegfact that strain on mount constructions can be largely eliminated by eliminating the necessity of bending the mount material at the conventional score lines utilized heretofore as hinges.

In mounts composed of two or moresuperimposed board that are bound together into aunit bya relatively th'in, flexible binding that extends'over and is-attached to the exterior surfaces of the mount, the bending stre es may be eliminated. by partially or completely severing the hinge line frornits base and by utilizing the relatively thin, flexible binding material as the. main hinge mediabout which such section may swing." The use of this simple concept has been complicated inits embodiment in mount constructions; how ever, by. the fact that manufacturing 'difficultie's in the way of many additional and separate operationsincrease the cost of the final product so reatly as to have precluded its'useheretofore. Furthermore, in hinged mount sections accord-' ing to the previous practice that utilized a score line on which-the hinged section swung, there hasbeen an inherent tendency for the hinged sectien to spring to an open or partiallyopen position unless thesame i held closed in a posiing and closing of the hinged section because the inherent'resistance' tothe flexing of the material atb tn'rem 3 Claims. (01. 403-152) The primary object of the invention is to provide mounts having hinged sections that are either partially or completely severedfrom the adjacent mount material and that are adapted for angular movement about a thin, flexibl hinge strip that puts no substantial strain on the adjacent mount structure.

Themanner in which this and other objects of the invention are accomplished will become clear by reading thefollowing description with reference to the accompanying drawings in which like reference numerals indicate like parts in the sev-. eral figures and in which:

As illustrated, the hinge line I2 is disposed horizontall across the width Lot the face board to provide a line about which a s V hinged section may be moved. It is obvious, of course, that should it be desired to have the hinged section swing about a vertical line, the line I2 would be disposed in a vertical position,

portions of the mount and from the further fact that the main hinge medium on which the same swings is that portion of the thin facing material.

the back board may be of the same contour as the is not desired, the hinged section is provided:

face board but, of course, this is not essential. In Figure 2 of the. drawings the back board isillustrated as having therein no precut hinge lines but in this connection it is to be noted that the form of the invention illustrated in Figures 7 through 12 may be practiced with respect to the back board It and the manner in which the method illustrated in these figures of the drawings may be practiced will becom clear from the description hereinafter.

It is customary to provide a facing for display mounts of various kinds and in many instances these faces, which generally consist of a thin, flexible and decorative material such as a leatherette paper, extend over theentire external surface of the mount and are attachedto the contacting surfaces throughout their areas. In Figure 3 of the drawings is shown a blank I6 cut of suitable decorative facing material and so shaped and notched as to permit the same to fold neatly and snugly over the surfaces of the mount. The face board It] and the back board Mare next assembled in superimposed relation after which the facing material 1 6 is attached to the external surfaces of theseboards thus forming a composite structure 18 as illustrated in Figure 4 of the drawings. It will be noted that the facing material l6 nowoverlies the precut hinge line l2 that previously has been formed in the face board. If the precut hinge line extends only partially through the board, the facing material will, of course, overlie the hinge line on the face of the board opposite that from which the out has been made. Subsequent operations are designed to produce the hinged section adapted to swing on that portion of the facing material l6 overlying the hinge line 12,

The hinged panel section 20 is now formed in the face board of the assembled mount elements and this section is formed by lines 22 that are cut through the facing material and the face board along suitable and predetermined contours and whose ends intersect the precut hinge line l2 at remote points as at 24 and 26. In the present case an indicia-display window 28 is formed in the hinged panel section 20 by cutting therefrom the body portion thereof preferably at the same time that the line 22 is cut through the facing material and the face board.- With this construetion it is evident that the hinged section 20 can be swung angularl about the line l2 without transmitting any stress or strain to that portion of either the hinged section or the face board lying on oppositesides of the hinge line l2. Manipulation-of the hinged section 20 can be ac- V ticularly, the back board 42 is provided with a complished for the purpose of inserting a pic.- 1

with one or more locking tongues 30 that are: adapted to engage complementary notches in the: adjacent surface of the face board. Thesee tongues 3b are preferably located at a point that;

is remote from the hinge line l2 and their con-- struction is such that the hinged section 21! is:

securely held in the plane of the face board by;

back board of such constructions, the entire susztaining strength of the back board retainedl' for the purpose for which the'same is intended*,; namely, the strengthening of the mount as at whole and the elimination of warping and tWiSj1ring frequently found in'constructions"whercini both the face board and'the back: board have: been somewhat weakened by; the cutting; f pass sages therethrough. I

The practice of the invention; may result in different types, of hinged sections and these sec tions may be located in the back board of the mount ,as shown in the modified form of the invention illustrated in Figures 7' through l2; In these figures of the drawings a face board 4 8 has been illustrated which in general construetion and contour corresponds to the face board l0. "A back board 42 is cut to :any desired or suitable contour and dimensions and herein the.

tions or supporting easels in the back board 42,

there is formed in thatback board one or more incisions extending therethroughor partially therethrough from the front to the rear and being adapted to form the linesin said board.-

about which such sections are to swing, P ar-- vertical incision 44 located substantially along; the medial lineof the board. The incision M,

in this case, is made for the purpose of providing an easel; and in order to provide a hinge li'i'ieifor; an easeliocking tongue therline M is intersected by a horizontal line 45. A picture-insertingdoor may be formed in'the back board can; swing about an incision 48.

The face board 4!! and'the backiboard ihare then superimposed and a flexible -binding mate rial 5B which has previously been" cut to the proper shape and size to permit the same to be:

folded about the exteriorcsurfaces orthe; super: imposed face board 4 0"and backboard-:isthen folded about. the surfacesv and the contacting areas of the-binding material and the. boards are attached to each other-asbygluing.

The unitary structure resulting from-the foregoing steps, and as :illustrated in FigurelOofthe drawings, is. then subjected to a further cutting noted that in the case of'each of cuts 52, 54 and 56 that they intersect the lines 44, 45 and 48, respectively, at remote points to define their respective elements. These operations result in a mount supporting easel 58, an easel locking tongue 66 and a picture-inserting door 62. The easel 58 is adapted to swing on the line 44, the easel locking tongue 69 is adapted to swing on the horizontal line 46 and the picture-inserting door 62 is adapted to swing along the vertical line 48. In operation, the manipulation of the easel, the easel locking tongue and the pictureinserting door places no strain on adjacent surfaces in either themselves or the surrounding back board.

In the preferred embodiment of the invention the margins 64 of the facing material 50 are adapted to fold about the edges of the boards 40 and 42 and to be glued against the face of the back board. The portion 66 of the flexible material 59 is then preferably folded over the back board in such manner that the margins thereof overlie the marginal edges 64.

The mount shown in Figures 13 to 15 of the drawings is constructed by precutting a hinge line 19 at least partially through the back board l2 and by assembling the back board 12 and a marginal spacing board 14 into superimposed relation whereafter the boards 12 and 14 are joined into a unit by means of a thin, flexible binding material 16, as in the previous practice of the invention. The extreme ends of the precut hinge line 19 are then intersected by means of an incision l8 extending through the binding material 76 and the back board 12, the incision 18 being of such contour as to provide a pictureinserting passage normally covered by a hinged closure 80. The closure 86 is adapted to swing angularly about the hinge line 10 and in Figures 13 and 14 the same is normally held in closed position by means of the complementary friction latches 82.

In that form of the invention shown in Figure 15, the closure fastener means is illustrated as consisting of a turn button 94 that is adapted to pivot on a turn button rivet 96, This form of closure fastener may be used advantageously because of the manufacturing advantages presented over previous mount passage closures that utilized turn button fasteners. With the closure 80 located near an edge of the mount panel and being adapted to swing outwardly about the weakened hinge line 10, it becomes possible to locate the turn button rivet 96 in that portion of the mount panel that lies entirely within the panel area defined by such marginal members as the spacing board 14 and the face board 84. In previous constructions it has always been necessary to resort to special manufacturing '6 marainto r; the, mg nt b h cknesses com l catederat,ior;1;. g

In this form of the invention it will be seen that a closure for a picture-inserting passage has been provided to swing outwardly on a precut hinge line thereby placing no substantial strain on that section of the back board adjacent the hinge line. The elimination of strain in mounts of this construction is-particularly important where, as in the present form, the hinged section is located near one of the marginal edges of the mount for when such sections are located near the marginal edges of a mount, there is usually an insufiicient. amount of material between such hinged section and the margin of the mount to stand the strain that would be 5W9; orig-l r b ar diet-inser in or:

inherent in the angular movement of such hinged I section about a score line.

The practice of the invention has been herein described in connection with the production of a specific mount but it is, of course, obvious that its teaching may be applied to the manufacture of different kinds of mounts.
